  vdat = FALSE,
  quiet = FALSE
)

Arguments

geom_path

path to a file to parse

units

units found in the project, "English Units" or "SI Units"

a projection string to apply

in_epoch_override

vdatum parameter input epoch, Default: as.integer(as.POSIXct(Sys.time()))

out_epoch_override

vdatum parameter output epoch, Default: as.integer(as.POSIXct(Sys.time()))

vdat

a flag to dictate whether or not to apply a vdatum transformation, TRUE to apply, FALSE to skip, Default: FALSE

quiet

flag to determine whether print statements are suppressed, TRUE to suppress messages and FALSE to show them, Default: FALSE
